How a cyanobacterium manages iron scarcity makes it the most successful photosynthetic organism on Earth
The sea is the world's largest ecosystem, and it harbors two photosynthetic organisms that produce approximately half of the oxygen on Earth. The cyanobacterium Prochlorococcus is the most abundant photosynthetic organism in the oceans and fixes appr.....»»
Study finds iron-rich enamel protects, but doesn"t color, rodents" orange-brown incisors
Chattering squirrels, charming coypus, and tail-slapping beavers—along with some other rodents—have orange-brown front teeth. Researchers have published high-resolution images of rodent incisors in ACS Nano, providing an atomic-level view of the.....»»

Study underscores uncertain costs of iron fertilization
As society grapples with the intensifying consequences of climate change, decision-makers are increasingly looking to carbon dioxide removal as a necessary complement to emission reductions. One of the strategies that has received the most attention.....»»
Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Antifungal activity of a maleimide derivative: Disruption of cell membranes and interference with iron ion homoeostasis
A small molecule library consisting of 40 compounds, specifically N-substituted maleimide and its derivatives, were initially screened in a study published in the journal Mycology, which was led by Prof. Ying Li (Xuzhou Medical University), Prof. Zuo.....»»
Scientists find one of the most ancient stars that formed in another galaxy
The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your ve.....»»
Iron restriction keeps blood stem cells young, researchers find
As we age, our hematopoietic (blood-forming) stem cells (HSCs) become less able to produce new red and white blood cells and other vital blood components—contributing to chronic inflammation and accelerating the onset of blood cancers and degenerat.....»»
Weird electron behavior gets even weirder: Charge fractionalization observed spectroscopically
A research team led by the Paul Scherrer Institute has spectroscopically observed the fractionalization of electronic charge in an iron-based metallic ferromagnet. Experimental observation of the phenomenon is not only of fundamental importance. Sinc.....»»

The bog is where forensics and archaeology meet to solve "cold cases"
Occasionally, police investigators find themselves announcing archaeological discoveries, rather than criminal findings. In 1984, for example, police oversaw the recovery of the Iron Age bog body (a naturally mummified corpse found in a peat bog) lat.....»»

Scientists develop new molecular system made from abundant element manganese for photooxidation
Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All.....»»
Charting the course to eco-friendly steel: China"s blueprint for cleaner air and a cooler planet
China, the world's top steel producer, is at a crossroads due to its iron and steel industry's heavy CO2 emissions and pollution contribution, spotlighting the urgent need for greener practices. This necessity stems from the industry's impact on air.....»»
Team describes how to produce "green" steel from toxic red mud
The production of aluminum generates around 180 million tons of toxic red mud every year. Scientists at the Max-Planck-Institut für Eisenforschung, a center for iron research, have now shown how green steel can be produced from aluminum production w.....»»
Understanding nutrient cycling between algae and bacteria could lead to increased biofuel production
The interactions between algae and bacteria are essential to the primary productivity of Earth's oceans and surface waters. Bacteria can increase the productivity of algae by producing key factors, such as vitamins, iron-chelating molecules, and grow.....»»
Planetary size and associated cooling rate may explain why Mars died while Earth survived
We know of Mars as the red planet, for its surface and atmosphere is caked in endless swirling dust of rusted iron, the rusting action provided by the always-eager oxygen. But this was not always so......»»
